Superhydrophobicity for Antifouling Microfluidic Surfaces

The document discussed the use of superhydrophobic surfaces to address fouling issues in microfluidic devices, particularly with protein or enzymatic solutions. It explored the potential of these surfaces to reduce surface contamination and enable self-cleaning under flow conditions. The study detailed the preparation of superhydrophobic coatings with micro- and nanoscale features and provided a method to quantify adsorbed protein at nanogram levels. The fabrication process involved silica sol-gel and copper nano-hair growth, applicable to various materials used in microfluidic devices.
